To @ZZ whom t may concern.'

Be it known that I, HARRY W. HAIGHII, a citizen of the United States, and a resident of Princeton, in the county of Mercer and State of New Jersey, have invented a new and Improved Printed Book, of which the following is a full, clear, and eXact description.

vThe object of the invention is to provide a new and improved printed book or block more especially designed for school purposes, and arranged to restrain a scholar or a reader fromlooking ahead of the page used at the time.

ln order to produce the desired result, the leaves of the printed book have applied thereto a fastening means such as glue or other adhesive substance, to fasten the leaves together along the sides, top and bottom, the fastening means having, at least, one interrupted portion to allow the insertion of a paper knife, pin or other tool or implement between adjacent leaves.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective view of the printed book;

Fig. 2 is a sectional plan View of the same on the line 2 2 of Fig. 3; and

Fig. 3 is an'end view of the same.

The printed leaves 10 of the book are held firmly together at one side of the book by stitching or other binding means, preferably between the front and rear covers 11 and 12 and the back 13. The leaves 10 are fastened together along the top and the righthand side by fastening means 14, such as glue or other adhesive substance,oand the leaves are fastened together along the bottom by similar fastening means 15. The fastening means 14 terminate at the top of the book a distance from the back 13, and

the fastening 'means 15 terminate likewise a distance from the back 13 of the book. The fastening means 14 and 15 at the right-hand side and the bottom of the book terminate a distance from the lower corner to permit the introduction of a paper knife, pin or other similar implement or tool between ad jacent leaves to break the corresponding portions of the fastening means 14 and 15 with a view to se ar-ate the uppermost leaf from the next fo lowing ones and thereby allow turning the leaf over in the usual manner. n i

The pages of the book present problem oi" problems or a problem or problems followed by corresponding answers and discussion, but normally the leaves are sealed and the scholar or reader is restrained from looking ahead ofv a page used at the time. The chief advantage of this invention is that the reader is restrained from looking ahead of the page which has been torn open last and it is especially useful in school work where the teacher wishes to secure individual expression in regard to a given problem which if given out in advance is likely to lead to one pupils copying the expression of another. It is also especially useful in school work where the printed answer or printed discussion follows the given problem because the reader is restrained from seeing the answer or discussion until the readers curiosity is aroused and until he has devoted thought to the problem. By terminating the fastening means 14 and 15 a distance from the back 13 of the book the tendency of tearing the leaves when opening the same is reduced to a minimum. It will also be noticed that by the arrangement described the leaves may be made of very thin paper and it is easy to open only one page at a time.

It is understood that the covers 11, 12 and the back 13 of thebook do not form a part of my invention, which relates only to the printed leaves 10, and the covers and back may be omitted and the leaves fastened together along the back by wire staplesor other binding means.

` Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. As an article of manufacture, a printed book comprising a plurality of superposed leaves of equal area permanently bound tov gether along one edge to form a back, and

fastening means applied to the superposed leaves along the top edges in an unbroken line from a point adjacent the back to the outer upper corner of the leaves and continuing unbrokenly along the side edges to a point adjacent the lower free corner of the leaves.

2. As an article of manufacture, a printed book consisting of a plurality of superposed leaves bound together at one edge to form a back, and fastening means applied to the leaves along the sides, top and bottom to fasten the leaves together at their edges and thereby hold the leaves against opening and preventing perusal Without separation of the leaves, the fastening means at the top and bottom terminating a distance from the back of the book, and the fastening means at the bottom of the book terminating a distance from the lower corner of the book and the fastening means on the outer side terminating a distance from the said lower corner, whereby the leaves at said lower corner are left free and unconnected.

3. As an article of manufacture, a printed book having a plurality of superposed leaves, and frangible fastening means applied along the edges of the superposed leaves continuously across the top of the book from a point adjacent to the back to the upper outer corner and down along the outer edges to a point adjacent the lower outer corner and then along the bottom edges from a point adjacent the lower outer free corner to a point adjacent the back of the book.
